It’s easy to connect sensors, and phones to communicate with other devices. Honestly, I can’t see any negatives. For tinkerers enthusiasts, this ESP32 board is a winner. It’s great for many projects due to it's diverse features. Also, the Arduino plays well with the IDE, allowing for faster development. Review: Absolute bargain - Disclaimer - I received a full refund after reporting a minor fault, making my unit effectively free. This is probably the lowest one-off price you'll pay for an ESP32. EPS32s a great. Highly recommended. It's a fully functional and easy to use Bluetooth/WiFi module with a micro-controller built in; or a micro-controller with a WiFi module built in - whatever way you want to look at it. Forget Arduinos and shields, this is everything in a tiny package. The hardware is open source (credit: Wei Wang/doit.am), so there are many variations to choose from. This PCB version is 0.1" wider than some ESP32 modules (see photo), which leaves rooms for mounting holes but with molex pins attached it's a row too wide for a standard prototyping board. Mine arrived with a fault in the molex pins, which were soldered on at a funny angle. I got a full refund without even asking for one so I can't fault the customer service. I'm assuming mine just slipped through quality control, but as I will probably remove the pins anyway (a complete pain to do) so I can attach wires to the PTH I could have lived with it. So in spite of the slight flaw, the customer service has restored it to five star. The extra width allows the edge pins to be silk-screened with labels, which is useful. Many of the pins are GPIO, and I believe there are three ACIAs (UARTS) built in; one of which is used by the USB via a converter chip. The whole thing runs beautifully cool. For software, the Arduino IDE "just works" with it, once you've installed the board package. And this includes complex libraries allowing you WiFi, DNS and IP socket drivers - including encryption on the WiFi and SSL. I absolutely love these boards. The picture is this board (right) next to a different, narrower, ESP32 board on the left. Both use the same ESP32 model at the centre. It shows the prototyping board problem, which is easy enough to overcome with a different prototyping board (or two of them). ## Features - The ESP-WROOM-32 is a powerful, versatile Wi-Fi + BT + BLE MCU general-purpose module that can be used for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding , etc. - The 2.4GHz Wi-Fi plus Bluetooth dual-mode chip is reliable, scalable and adaptable. Two CPU cores can be controlled or powered individually. - Small volume, easy to integrate with other products. ESP32 integrates antenna switches, RF baluns, power amplifiers, low noise amplifiers, filters and power management modules. The complete solution occupies the smallest area of the printed circuit board. - The user can turn off the CPU power and use the coprocessor at low power to continuously monitor the status of the peripherals or if some of the analog values exceed the threshold. - ESP32 also integrates a large amount of peripherals, including capacitive touch sensors, Hall sensors, low noise sensor, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071JR9WS9 | | Box Contents | 1 x ESP32 development module | | Brand Name | JZK | | Compatible Devices | Smartphone, Personal computer, Camera | | Country of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (771) | | Manufacturer Part Number | JZK-75639 | | Memory Storage Capacity | 4 MB | | Model Name | ESP-32S | | Model Number | JZK | | Network Connectivity Technology | Bluetooth | | Operating System | Linux, Windows | | Processor Brand | Espressif Systems | | Processor Count | 2 | | Processor Speed | 8E+1 MHz | | RAM Memory Installed | 520 KB | | RAM Memory Technology | SRAM | | Total USB Ports | 1 | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** JZK - **CPU speed:** 8E+1 MHz - **Memory storage capacity:** 4 MB - **Model name:** ESP-32S - **RAM memory installed size:** 520 KB ## Images ![JZK ESP-32S ESP32 Development Board 2.4GHz WiFi + Bluetooth Dual Mode Antenna Module with Ultra Low Power - Image 1](https://m.media-amazon.com/images/I/71SyCCoTfML.jpg) ## Questions & Answers **Q: In the arduino ide, after getting the esp32 board modules, there is a very long list of different types. which should be selected for this board?** A: DOIT ESP32 DEVKIT V1 is the board I use that works with this module. **Q: Is there a board manager for this to build with arduino ide?** A: Yes there is a module you can install in Arduino IDE called ESP Dev Module. Also you can use this libray https://esphome.io/ **Q: Can you use the arduino ide with this board? is esplorer an alternative to the arduino ide, what's the benefit of one vs another with this board?** A: Yes you can use the Arduino IDE with this board. Never heard of esplorer, have not used it so cannot compare the two. I've never had any issues with Arduino IDE though. **Q: I have windows 10 and just doesn't recognise the board I've tried all drivers old and new, any ideas?** A: I use win 10 and it works with the Arduino compiler, which has the Esp32 library installed. I had a similar problem once, which was the usb cable. It turned out to be a 'Charge Only' cable, which didnt have the signal wires. So the PC could not 'see' the esp32.

USB takes care of the reboot on code deployment, so you don't often have to hit the "boot" or "EN" buttons. can't find schema to control the red "always on" LED, however there's a small blue onboard LED which maps to GPIO-2. Never used these boards before but had it up and running, controlling LED, LCD panel and interfaced to home wifi within a couple of hours. ## Frequently Bought Together - JZK ESP-32S ESP32 Development Board 2.4GHz WiFi + Bluetooth Dual Mode Antenna Module with Ultra Low Power - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/52056393-jzk-esp-32s-esp32-development-board-2-4ghz-wifi-bluetooth](https://www.desertcart.gr/products/52056393-jzk-esp-32s-esp32-development-board-2-4ghz-wifi-bluetooth) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-05*
